Version: ImageMagick 7.0.7-39 Q16 x86_64 2018-06-11
EDIT: Platform macOS

I'd like to use the montage command to create a single image where each panel has its own different text label.

I'm more familiar with the -draw "text.." command than the -label command, but I dismissed the -label command as not for me because the examples site showed the results as a sort of extra panel at the bottom. I will use -draw or -label or whatever is recommended. What I want is shown here with both an incorrect and a correct result in the two different images:

EDIT: Although my boiled-down code examples below use xc:color, in real life I am doing this with image files as input, not just xc:color. I think that should not change the answer though.

Here's what I tried (in bash shell script form):

Code: Select all

# bad result
montage -geometry 200x200 -gravity center -stroke none -fill white -pointsize 48 \
    xc:blue -draw 'text 0,0 "Panel 1"' \
    xc:red -draw 'text 0,0 "Panel 2"' \
    xc:yellow -draw 'text 0,0 "Panel 3"' \
    xc:purple -draw 'text 0,0 "Panel 4"' \
    xc:green -draw 'text 0,0 "Panel 5"' \
    xc:black -draw 'text 0,0 "Panel 6"' \
    -mode concatenate -tile 3x2 using-montage-alone.jpg

I can get the results I want by first using convert to make temporary labeled images, and then using montage to combine those temporary images, like this:

Code: Select all

# good result
spec="-geometry 200x200 -gravity center -stroke none -fill white -pointsize 48"
for color in {blue,red,yellow,purple,green,black}; do
    panel_number=$((panel_number + 1))
    text_spec="text 0,0 'Panel "$panel_number"'"
    convert xc:$color $spec -draw "$text_spec" panel-$panel_number.jpg
done
montage panel-{1..6}.jpg  -mode concatenate -tile 3x2 resorting-to-convert-first-then-montage.jpg

So yes I will do that in the meantime. But my question is, can this be done with montage alone? And how?

In IM 7, you need to preface montage with magick, so

magick montage ....

Try this:

Code: Select all

magick montage \
-gravity center -stroke none -fill white -pointsize 48 \
-size 200x200 \
\( xc:blue -draw "text 0,0 'Panel 1'" \) \
\( xc:red -draw "text 0,0 'Panel 2'" \) \
\( xc:yellow -draw "text 0,0 'Panel 3'" \) \
\( xc:purple -draw "text 0,0 'Panel 4'" \) \
\( xc:green -draw "text 0,0 'Panel 5'" \) \
\( xc:black -draw "text 0,0 'Panel 6'" \) \
-mode concatenate -tile 3x2 using-montage-alone.jpg

That works for me on IM 7.0.8.5 Q16 Mac OSX Sierra

Thanks! That works great for me too.

P.S. I think the issue you had was that you needed to use parentheses to keep the text from accumulating over itself. Also I generally do not recommend using -geometry for resizing in montage, only for spacing.

That parens trick is new to me. Very useful, thanks. And -geometry versus -size always confused me. I'll get it one of these days!

Also btw it seems stuff still works on my system without the magick preface, but I take it things are heading that direction so I'll start updating scripts to use that.

Do you have both IM 6 and IM 7 on your system? If so, then leaving off the magick and using just montage would work using IM 6.
